[SOLVED] Admin form action issue with Cancel toolbar button - Joomla! Forum - community, help and support

hi all, , best wishes 2013!

i'm developping custom component, , have issue on admin side.

i have first default page list of uploads (id, file_name, etc).
when click 1 entry, go second view, "validatefile".

on second page, want add cancel button on toolbar, able te return list.
so here's i've done far.

in "validatefile" view (view.html.php), have added toolbar jtoolbarhelper, , added toolbar button this:

code: select all

jtoolbarhelper::cancel('validatefile.cancel', 'jtoolbar_cancel');

in default template (default.php), have :

code: select all

<script type="text/javascript">
    joomla.submitbutton = function(task)
    {
        if (task == 'validatefile.cancel') {
            joomla.submitform(task, document.getelementbyid('validatefile-form'));
        }
    }
</script>

<form action="<?php echo jroute::_('index.php?option=com_dropfileszone&view=adminlistv1ew'); ?>" method="post" name="adminform" id="validatefile-form" class="form-validate">
    hello world

    <input type="hidden" name="task" value="" />
    <?php echo jhtml::_('form.token'); ?>
    <div class="clr"></div>
</form>

ok page shows "hello world" , cancel button, dummy code here perform form submission.

when click on cancel toolbar button, form action 'option=com_dropfileszone&view=adminlistv1ew' executed, can see blank page blank toolbar (see attached file).
although url enough : administrator/index.php?option=com_dropfileszone&view=adminlistv1ew.
because when refresh page, list !

the workaround have found override cancel method in 'validatefile' controller :

code: select all

    function cancel() {
        $this->setredirect(jroute::_('index.php?option=com_dropfileszone&view=adminlistv1ew', false));
    }

so php setredirect function working, not form action.
can point me if i'm doing wrong, of if there's better way ?
i'm sure missed something, , missunderstood joomla mechanism

any appreciated

please use jtoolbarhelper::back() instead. check http://docs.joomla.org/jtoolbarhelper/back
